Coxiella burnetii is a human pathogen that causes the serious zoonotic disease Q fever. It is ubiquitous in the environment and due to its wide host range, long-range dispersal potential and classification as a bioterrorism agent, this microorganism is considered an HHS Select Agent. In the event of an outbreak or intentional release, laboratory strain typing methods can contribute to epidemiological investigations, law enforcement investigation and the public health response by providing critical information about the relatedness between C...

Melioidosis is a frequently fatal infection caused by the Gram-negative bacillus Burkholderia pseudomallei endemic to Southeast Asia and Northern Australia. It is a rare imported pathogen in the United States and is a potential bioterror agent. We report the case of an 82-year-old previously healthy man who presented with 2 weeks of fever and epigastric pain after he returned from the Philippines. A diagnosis of nondissecting mycotic aneurysm in the descending thoracic aorta was made with the help of CT angiogram and positive blood cultures...

Monkeypox is a smallpox-like illness that can be accompanied by a range of significant medical complications. To date there are no standard or optimized guidelines for the clinical management of monkeypox (MPX) patients, particularly in low-resource settings. Consequently, patients can experience protracted illness and poor outcomes. Improving care necessitates developing a better understanding of the range of clinical manifestations-including complications and sequelae-as well as of features of illness that may be predictive of illness severity and poor outcomes...

Bacillus anthracis is the causative agent of the deadly disease Anthrax. Its use in bioterrorism and its ability to re-emerge have brought renewed interest in this organism. B. anthracis is a Gram-positive bacterium that adds L-rhamnose to its cell-wall polysaccharides using the activated donor dTDP-β-L-rhamnose. The enzymes involved in the biosynthesis of the activated donor are absent in humans, which make them ideal targets for therapeutic development to combat pathogens. Here, the 2.65 Å resolution crystal structure of the fourth enzyme in the dTDP-β-L-rhamnose-biosynthetic pathway from B...

Botulinum neurotoxins (BoNTs), the most potent toxins known, are potential bioterrorism agents. It is well established that all seven serotypes of BoNTs (BoNT/A-G) require complex gangliosides as co-receptors. Here, we report that BoNT/DC, a presumed mosaic toxin between BoNT/D and BoNT/C1, binds and enters efficiently into neurons lacking complex gangliosides and shows no reduction in toxicity in mice deficient in complex gangliosides. The co-crystal structure of BoNT/DC with sialyl-Thomsen-Friedenreich antigen (Sialyl-T) suggests that BoNT/DC recognizes only the sialic acid, but not other moieties in gangliosides...

Anthrax, caused by Bacillus anthracis, is considered a severe bioterrorism threat because of its high mortality rate. The Chicago Healthcare System Coalition for Preparedness and Response (CHSCPR) aims to pre-position antibiotic medical countermeasures (MCMs) at healthcare facilities in order to provide on-site anthrax post-exposure prophylaxis. Pharmacists proposed moving toward a new process that involved the development of a standardized calculation methodology for acquiring supply drugs. This was an interventional quality improvement project aimed at optimizing inventory, acquisition, and distribution of antibiotic MCMs for anthrax post-exposure prophylaxis at Chicago hospitals for hospital personnel, associated first responders, and their families...

Portable analytical devices are notably gaining relevance in the panorama of urgent testing. Such devices have the potential to play an important role as easy-to-handle tools in critical situations. Epidemic infectious disease agents (e.g., Ebola virus, Coronavirus, Zika virus) could be controlled more easily by testing travelers on-site at the country borders to prevent outbreaks from spreading. The increasing incidence of hospital-acquired infections caused by antibiotic resistant pathogens could be minimized by point-of-care microbial analysis as well as rapid screening tests of bacteria resistance...

Abrin, one of the most highly potent toxins in the world, is derived from the plant, Abrus precatorius. Because of its high toxicity, it poses potential bioterror risks. Therefore, a need exists for new reagents and technologies that would be able to rapidly detect abrin contamination as well as lead to new therapeutics. We report here a group of abrin-specific monoclonal antibodies (mAbs) that recognize abrin A-chain, intact A-B chain toxin, and agglutinin by Western blot. Additionally, these mAbs were evaluated for their ability to serve as capture antibodies for a sandwich (capture) ELISA...

Marburg virus (MARV) is a highly lethal hemorrhagic fever virus that is increasingly re-emerging in Africa, has been imported to both Europe and the US, and is also a Tier 1 bioterror threat. As a negative sense RNA virus, MARV has error prone replication which can yield progeny capable of evading countermeasures. To evaluate this vulnerability, we sought to determine the epitopes of 4 llama single-domain antibodies (sdAbs or VHH) specific for nucleoprotein (NP), each capable of forming MARV monoclonal affinity reagent sandwich assays...

Abrin, one of most potent toxins known to man, is derived from the rosary pea (jequirity pea), Abrus precatorius and is a potential bioterror weapon. The temperature and pH stability of abrin was evaluated with an in vitro cell free translation (CFT) assay, a Vero cell culture cytotoxicity assay, and an in vivo mouse bioassay. pH treatment of abrin had no detrimental effect on its stability and toxicity as seen either in vitro or in vivo. Abrin exposure to increasing temperatures did not completely abrogate protein translation...

Recent zoonotic outbreaks, such as Zika, Middle East Respiratory Syndrome, and Ebola, have highlighted the need for rapid and accurate diagnostic assays that can be used to aid pathogen control. Q-fever is a zoonotic disease caused by the transmission of Coxiella burnetii that can cause serious illness in humans via aerosols and is considered a potential bioterrorism agent. However the existing assays are not suitable for the detection of this pathogen due to its low levels in real samples. We here describe a rapid bio-optical sensor for the accurate detection of Q fever and validate its clinical utility...

Matrix-assisted laser desorption ionization -- time of flight mass spectrometry (MALDI-TOF MS) sample preparation methods including the direct, on-plate formic acid, and ethanol/formic acid tube extraction were evaluated for their ability to render highly pathogenic organisms non-viable and safe for handling in a Biosafety Level-2 laboratory. Of these, the tube extraction procedure was the most successful, with none of the tested strains surviving this sample preparation method. Tube extracts from several agents of bioterrorism and their near neighbors were analyzed in an eight laboratory study to examine the utility of the Bruker Biotyper and Vitek MS MALDI-TOF MS systems and their IVD, research use only, and Security-Relevant databases, as applicable, to accurately identify these agents...

Francisella tularensis is the causative agent of tularemia and a potential bioterrorism agent. In the present study, we isolated, identified, and quantified the proteins present in the membranes of the virulent type A strain, Schu S4, and the attenuated type B strain, LVS (live vaccine strain). Spectral counting of mass spectrometric data showed enrichment for membrane proteins in both strains. Mice vaccinated with whole LVS membranes encapsulated in poly (lactic-co-glycolic acid) (PLGA) nanoparticles containing the adjuvant polyinosinic-polycytidylic acid [poly(I·C)] showed significant protection against a challenge with LVS compared to the results seen with naive mice or mice vaccinated with either membranes or poly(I·C) alone...
